Definitions
- the invention relates to composite security documents and to methods for producing such composite security documents which comprise a document body, wherein the document body is a monolithic laminate body produced from a plurality of layers.
- security features may be incorporated so that they can be used as identification documents, e.g. Identity cards, driving licenses, but also in passports, and other documents are used in which a high anti-counterfeiting value is placed.
- identification documents e.g. Identity cards, driving licenses, but also in passports, and other documents are used in which a high anti-counterfeiting value is placed.
- watermarks are made by structures that are located in a sieve, with which the pulp is scooped out of the water. At locations where the screen is raised, fewer fibers accumulate than at those locations where the screen has recesses. There are more fibers collecting. At the points where there are fewer fibers, the paper is more transparent than at those points where more fibers have collected. In transmitted light, the watermark without technical aids is also easy to recognize for a layman. Modern paper mills are able to display patterns, characters and other graphic representations in different shades of gray. As a result, a simulation of a watermark, eg by an oily substance, almost impossible.
- Layers or foils that are laminated to one another have a greater extent than along the lamination direction, so that the resulting composite security documents have a card shape.
- plastic-based documents are known from the prior art, as they are used, for example, for credit and debit cards, but also as identification documents, e.g. for identity cards and driving licenses, etc., find use.
- One of the most suitable manufacturing methods for such plastic-based documents is a laminating method of layer or stack construction in which individual layered layers, such as plastic films, are heated above their glass transition temperature and subjected to high pressure for a long time to form the individual layers to the monolithic card body to merge.
- no methods are known to incorporate a watermark comparable security feature in the cards.
- embossing plates which emboss structures in the outer layers, for example lens structures, in order to produce an angle-dependent representation, as described, for example, in DE 199 49 945 or DE 100 36 505.
- a disadvantage of these embossments is that the stamping plates are very expensive to produce, since the Himalayagenden structures must protrude as negative structures from the plate surface, which makes a production very expensive.
- embossing plates are subject to high wear.
- a simple variation of the Himalayagenden structures is therefore not readily possible, as each new stamping plates must be made.
- a small series production of individualized security documents with embossed structures is therefore not possible according to the current state of the art at a reasonable cost.
- the invention is therefore based on the technical object of composite security documents, which is a document body, which is a monolithic laminate body produced from several layers, with a Bundeschristerei GmbH P11.31 OWO / BD 0128/07 watermark-like security feature, and to provide a method for its production, which eliminate the disadvantages described above and in particular allow individualization of the composite security elements in a simpler manner.
- the invention is based on the idea, inside the
- Laminated security document to create hollow-relief-like structures For this purpose, it is provided according to the invention to create one or more empty cavities in the layer or stack structure prior to lamination. These cavities can be created by recesses in the material to be laminated of the layers. As an empty recess or empty cavity, one is considered which has no material to be laminated or another material in the stack construction and is completely surrounded by plastic material to be laminated. The resulting from the empty recess during lamination structure is referred to as a hollow relief-like structure.
- the security feature formed in the composite security document is referred to as a hollow-relief-type structure.
- a composite security document having an internal hollow relief-like structure
- a document body being a monolithic laminate body made of several layers
- the document body comprising at least one hollow-relief-like structure used in a high-temperature, high-pressure lamination process, from an upper and lower side, formed on a layering direction of the layers, formed in at least one of the layers before the lamination process empty recess is formed.
- a method for producing a composite security document with a document body comprises the following steps: providing a plurality of layers, arranging the plurality of layers one above the other, and laminating the plurality on top of one another Bundeschristerei GmbH P11.31 OWO / BD 0128/07 arranged in a high-temperature high-pressure lamination process to a monolithic card body, wherein at least one of the plurality of layers at least one recess is introduced and the plurality of layers are arranged so that the at least one recess is completed to a top and a bottom of the stacked layers and the volume of the recess is empty and the empty recess is preferably evacuated and the lamination is carried out so that a hollow-relief-like structure is formed in the card body.
- the new realization is exploited that above the glass transition temperature of the plastics to which the layers are heated in the high-temperature high-pressure lamination process, can be kept in a viscosity range, which causes a complete fusion of the layers arranged one above the other, however The result is that the empty recesses and cavities are not filled so completely by material of the layers that the contours of the recess completely disappear.
- the plastics are also above the glass transition temperature and at high pressures unable to fill the recess leveling with material, as would be expected for a low viscosity liquid. The recess can therefore be seen slightly lowered with running contours.
- Recesses can be formed by depressions, ie recesses which do not completely break through the respective layer. Furthermore, recesses may be formed by apertures that completely penetrate a layer and form a passage opening in this layer or represent. Breakthroughs can be made in different ways. Recesses may also be formed by a combination of perforations and depressions in different layers or be. Bundesbuchisme GmbH P11.31 OWO / BD 0128/07
- the recess is formed in at least one layer lying in front of the lamination. This ensures that the inner hollow-relief-like structure protrudes deep into the document body viewed from one of the surfaces.
- the recess formed in the inner layer is formed by means of an opening or comprises an opening which penetrates completely through at least one layer, ie. a passage opening through the layer.
- the at least one recess comprises at least one opening through at least one layer lying inside during the stratification.
- the at least one recess is formed in such an embodiment by introducing into at least one of the layers, which is or will be an inner layer, an opening completely penetrating the respective layer.
- the hollow-relief-like structure comprises a recess perceptible on one of the surfaces.
- a surface-perceptible recess can also be achieved in manufacturing processes in which the recess prior to lamination is deposited only in internal layers, i. is not formed in the layer disposed on a surface of the document body.
- the advantage of such an embodiment is that the hollow-relief-like structure is perceived not only visually, but also tactile.
- portions of a material from which the layers are formed above and / or below the recess are used in addition to the material of the layers in which the recess is located to fill the recess.
- "contour changes" thus occur in layers arranged above or below.
- an optically variable security feature is incorporated in a region of the at least one hollow-relief-like structure, in particular by a structure with an interference color in a hollow relief-like structure overlapping area printed layer is incorporated between the original recess and the outside of the document body.
- An optically variable security feature is understood to be any security feature that produces a different impression as a function of a viewing direction. For example, an interference color changes its perceived color depending on the viewing angle.
- the security feature is not only visible in a grainy viewing of the document. In the area of the hollow relief-like structure, therefore, different colors appear without the need to change a viewing angle of the document. Thus, a verification of the hollow-relief-like structure is greatly simplified.
- the optically variable security feature is also incorporated in an inner layer, so that a tamper resistance and protection against wear are increased.
- the at least one hollow-relief-like structure has regions of different material thickness with respect to the direction of the layering, apart from an edge contour.
- the recess in different areas which are not edge regions of the recess, ie, are not regions that indicate a contour of the recess in plan view, different thicknesses, with respect to a direction of lamination of the individual Bundesbuchisme GmbH P11.31 OWO / BD 0128/07 has laminated layers on top of each other.
- An optical perceptibility is increased by the fact that above or below the recess, an opaque layer, which may be printed, for example, is arranged. That is, preferably, before the lamination, an opaque layer or at least a part of an opaque layer is disposed between the recess and a surface of the layer stack.
- a grayscale watermark-like structure can also be introduced into a document body if the document body is formed with at least one further hollow-relief-like structure formed by at least one of the preferably inwardly located layers prior to lamination, which is geometrically configured , in particular their extent, with respect to the layering direction, from which distinguishes at least one hollow-relief-like structure.
- the plurality of hollow-relief-like structures arranged in a pattern preferably have different dimensions along the direction of the lamination. The greater the extent along the direction of the layering, the more the layers arranged toward a surface of the document body can be influenced and changed in the region of the recess during lamination.
- the plurality of hollow-relief-like layers preferably lead to different thicknesses of the card document at the different hollow relief-like structures.
- the recesses can be produced in a particularly simple manner by punching out internal layers. Punches are particularly easy to make breakthroughs.
- the advantage of using punched-outs is that they can be easily introduced and a plurality of punch-outs can be made to produce a pattern in a layer. A variation of the pattern is easily possible.
- the at least one recess and / or the at least one further recess are formed by superimposed punches of a plurality of inner layers.
- the at least one recess and the at least one further recess are punched out and additional recesses are introduced into at least one further layer and the at least one layer and the at least one further layer are arranged as inner layers during the layering in such a way that they are covered
- different numbers of recesses and / or different deep recesses are arranged one above the other, so that form different hollow-relief-like structures of the at least one recess and the at least one further recess.
- Grayscale can be generated in a punched pattern, for example, by punching in several of the layers recesses, so that when stacking Bundesdruckerei GmbH P11.31 OWO / BD 0128/07 of the several punched layers, as the inner layers at different locations, different numbers of punched-outs are arranged one above the other.
- different hollow relief-like structures form in the document body.
- the hollow-relief-like structures in different structures ie in different planes perpendicular to the layer plane, may be formed in the document body.
- apertures made in a similar manner to apertures may be used to create recesses of varying depth in a stack of layers prior to lamination.
- Recesses can be introduced into the layers not only by punching, but also all other techniques can be used, which can effect a layer thickness modulation. These preferably include, in addition to punching, engraving, different laser processing techniques, etc.
- diffractive surface structures are produced on at least one surface of the document body by means of the hollow-relief-like structures.
- Advantage of this embodiment is that simple punched can be used to produce diffractive surface structures. Elaborate printing plates or stamping plates, as used in the prior art, are not required for this purpose.
- a contrast-generating material This may be a paint or paste comprising, for example, metallic particles, carbon black or the like. Such an embodiment is able to produce a contrast even in transmitted light. By choosing the filling material, it can be determined whether a contrast in the visible range, UV range or in the infrared wavelength range is formed.

- the layers are pressed together by high pressure. The pressure is applied parallel to a direction of lamination 11. That is, the upper layer 3 and the lower layer 7 adjacent elements exert a pressure on the films, so that they are pressed parallel to the laminating direction 11 to each other. In this case, pressures of more than 50 bar are typically used.
- the T-shaped recess is not completely filled by material of the middle layer 5 as well as material of the overlying layer 4 and underlying layer 6 so that a homogeneous card body in the region of the recess results. Rather, a hollow-relief-like structure remains e, which is created by the fact that parts of the material of the overlying layer 4 and / or the underlying layer 6 are quasi drawn into the recess 9.
- the originally T-shaped contour 12 of the recess 9 washed out is still discernible as a blurred or washed-out contour 13. This is indicated in Fig. 1c by a dashed representation of the washed-out contour 13.
